PIN TUBE.

Application filed April 18, 1928. Seria1 N0. 279,860.

'Ihis invention relates t certain new und useful improvements in a ta.b end pin tube, so cailed the function of which is t0 properly support the pin ortion oi? a saiety pin 01 the like in such nmnner that it will not buckle when under st-rain in use.

T he object 015 tne invention is top1ovide an exceedinging simple, easily nmnufact und, cheap, yet efi'icient tab end pin tube structme.

In t-he accornpanying dvmvings- Fig. 1 ist a. front viow of the complele tab end as in use with a safety pin;

Fig'. 2 is an end elevation of tbe pin tube itself and its supporting tab;

Fig. 3 is a lan view of the blank which the pin tube is formal;

Fig. 4: is end view 01 21 modifi-cation.

1 represents a tab of fabric. The pin tube, so called, in its compleced fo1m provides the tube portion l and the slotted tab receiving; und gripping portions 2 3.

Referring to the blank shown in Fig. 3, 45 represent slots adjacent the opposite edges tbereof through which the two end% of t-he tab 1 may be slipped, aftr Wh'i.0h tbe blank ma.y be 1011ed up so r0 fornn a tube 6, :1s

from

illustmte in I*i 2 and 4, those portions of tho blank outside 0'f tbe s1ots consti.tuting glipping portions 01 b2u's which pinch down upon and hold together the two ends: of the tab. The intennediate portion o'f the tab Will be seen t0 surround and substantially cove'r tha outside of the pin tube portion. By this construction, pin tubes with tab ends attacbed thereto ready t0 be sewed an t0 garment-s nmy be very rapidly und oconmnically produced.

Referring t0 Fig. I, .it Will be noted that tbe blank is shown as f01ded 11 so that tbe two (ab gripping porfions 01 bars outside 0'! tbe slots d'o n0t face 'eacb orher as in Fig. 2 but mre located one above the othe1, this view being shown merely t0 illusate the fact that the particular line 011 which Ehe blank is rolled up to f01m the tubc passage iss not necessarily midway between the slots.

In use, whensuch a Bube is secured t0 a garment by 1neans of the tab 01' otherwise, as shown in Fig. 1, ift furnishes a supporting 1neans threugh which tbe pin ortion 7 0'f a saiety pin may be easily passed so tbat when it is locnted therein it Will be bald agai1'lstbnckling when straln is applied 110 Ehe safety p1n.

It Will be noted that in forming the s1-0ts 45 tb.e meta1 blank is preferably slitted as shown in Fig. 3, in such a manner as to forma 1ips 9-10 which serve 110 complete the tube when it is rolled up as shown in Figs. 2 and 4.

VVhat I claim is:

1. A pin tube formed 0f astrip 0f metal having two spa-ced slots adj acent the opposite edges thoseparts 0i the strip outside of said slots forming tvv0 gripping portions the intermediate porc-ion 01. said strip between sind s10ts forming a tubular pin assage.

2. In a device 0f Ehe cbamcter described,

a sheetmeal strip having two s1ots tberein adjacent the opposite edges tbereof, tbe in* temnediate portion 0f said strip betwen S{Li(1 slors forming a p'in aube, a strip 0f fabric extending around the outside 0f sai.d tube portion, tbe two ends 0f said fabric strip passing through said slors, und being located between tbe two edges of the metal strip outside 015 the slots und he1cl thereby.

3. A. pin tube formed 0f a folded n1etal strip hzwinp; therein two substantially paral- 191 s1ots, and a pin passage in the fold of the strip between tbe said sl0ts.

4. A pin tube formed 0E. 21 'I'01'd0d metal strip having therein tw0 substantialiy parallel slots, a pin passage in tbe fold of the strip between the sa-id slots, and bendable 1ips ad jacent 120 said s1ots.
